TPIS 90mm ls6 intakes I was looking at the best intake for the buck since fast IS so expensive and i think everyone tis one a budget these days.
TPIS takes a ls6 and cuts the throttle body mount off and plaastic fuses a 90mm throttle body plate mount to the ls6 and there 90mm throttle body, claims with dyno sheets that it out performs the FAST from 2200-6700rpms and its only 350 to have them do this compared to 1000 bucks for A FAST.
I wanna look into this more if anyone out there has done this and is the any links you guy know of to look at?

I plan on going this route as well. Lingenfelter has a comparison on their site and its w/in a few hp of the FAST. Since I only shift @ 6400 I wont really benefit much from the FAST, so I figure TPIS ($350) + $400 tb= $750, or a FAST/tb combo for $1100. I'd rather save $350.

but...
assuming you have the ls6 now, when you sell it after installing the FAST, you are down to $800 out of pocket for the intake....take another $50-100 for selling the stock ls1 TB. so really you can get into a FAST setup for about $750
or spend the same amount on the modified LS6 + bigger TB.
i just picked up a used FAST 9090 setup, mild port by LPE, for $1200 shipped, and it included bosch green top injectors.
so selling my ls6, TB, and possibly the injectors (little more than i need, and could use the money)....i'm getting a FAST setup for about $500 out of pocket.
good deal in my book

I can tell you that from my airflow measurements made through tuning software, that going the TPIS route is an excellent choice. I would suggest their 75x90mm inlet option w/ a Summit or other inexpensive 85mm TB kit as the least expensive option.
My modified LS6 intake produces airflows similar to what is noted on the 90mm & 75x90mm TPIS comparison charts & is modified in a fashion that was expected to produce similar results. So, even though I have not tested their exact design, their methods produce results that would be expected, from what I have tested. Further, the area I have tested ranges from 2800-6300 RPMS through the mods listed in my signature.
Have said this many times before; the LS6 intake is the best option up to 6300 RPMS on stock cubes. Don't ever let anyone touch the runners, it's effectiveness is based on the higher velocity of air that it moves through those runners. Opening the runners will only slow the airspeed that the LS6 relies on to be the performer that it is. I personnaly do not believe that the "Street Warrior" will be any better. It's testing was done on other than stock set ups, was measured @ the crank (not RWHP ot TQ) & my testing demostrated that their existing aluminum version (Weiand) relies more on air volume than airspeed, which is why I have said that the aluminum version is a better forced air or Nitrous set ups. Don't let marketing push you into a less than ideal choice. GM should be commended for applying what had been learned from the LS1 & applying it to produce the excellence of the LS6 intake. The TPIS version is as good as the LS6 gets, on stock cubes up to 6300 RPMS.
Appologies for the long post.

Hell i didn't think id get this good of a respons out of this thread but good info....In my opinon even if the FAST out performs the TPIS ls6 90 its only from 6500 up unless your reving out to 7500 the time your between 6500 and 7000rpms is very min. compared to 2000-6500 i would rather produce more power between 2000-6500 than 6500-7000 just like a 60ft time is important in the 1320 getting your engine to rip threw 2000-6500rpm faster is better than 6500-7000 thats only 500rpms compared to 4500rpms

One other thing ive read the FAST with a h/c car only makes 4more hp between 6500-7000rpm who wants to pay $350 for 4hp spend less money on the tpis 90mm and put the $350 bucks you save into something else on the car and get more power out of it. Im suure your $350 well spent some other way.
